Is my axolotl sick?

[Hesskat]

Hey, so I have had my axolotl for about 5 years and he is about 6 years old now. Recently he started getting these little white spots. He was born with some specks of gold on him, however these spots began to appear every few months and now they just keep popping up out of nowhere. I’ve tried to research what it may be, but kind of had no luck. Is he just getting old? Could it be a disease? Water levels/temps/feeding schedule is all good. I just have no clue what it could be. Any insight would be much appreciated.
Thank you,
Katheryn

unless the spots are pronounced they tend to be quite harmless and just areas that have lost their pigmentation.
